I updated to 1.8.5 with no problem following the usual steps. When I inserted the same card into our back up Buddy nothing happened. Its still at 1.7.7 and I’m not sure how to update it. There is no reference in the tutorial video for this.
Try this: reload the 1.8.5 firmware files to your SD card and try again with the backup pedal.
Once again…not only are you quick to respond and bail me out but dead on. Maybe I should start having more difficult problems to keep you challenged?
